EXPRT RF-20AS Whole House Water Filter Cartridge - High Capacity 20" x 4.5" 10 Micron Anti-Scale Water Filter - Polyphosphate Water Filter - Inhibit Corrosion on Iron, Copper, Lead Pipes & Plumbing
● Prevents scale from forming in your pipes and clears partially clogged pipes. Protect your home appliance, faucet fixture, and plumbing from scale build-up.
● Anti-scale media creates a coating on the surface of the pipe which prevents corrosion on iron, lead, galvanized, steel, and copper. If you have chlorine in your water, this coating can help stabilize the chlorine in your water as it will not react with the metal pipe. Universal standard size, all common 4.5 x 20 inch water filter system housings are compatible with EXPRT's 20 inch water filter cartridge replacement.
● The anti scaling filter delivers high flow rates & very low pressure drop. The whole house filter requires a feed water pressure of 80 PSI to produce a flow rate of 12-15 GPM. It also has a large water filter life span of about 10-12 months. (May vary depending on the quality of the feed water.)
● The 4.5” x 20” water filter cartridge is individually wrapped. Lifetime free tech support from US local support team. We stand behind our products and if you encounter any problems, please reach out to us immediately. We are happy to help!
● ATTENTION⚠️Each whole house descaler filter is manufactured with polyphosphate and is able to achieve filtration down to 10 microns. Unlike an RO membrane, the replacement water filters don’t reduce Total Dissolved Solids (TDS). If you are interested in TDS removal, consider our EXPRT Reverse Osmosis (RO) systems.
